engaging the work, and by setting the bed in motion the work may be fed to the cutters, meantime the cutters are being rotated by means of a belt 01 applied to pulley I.

In Fig. 3, L represents a chase. The dotted lines Z Z along the sides, and the dotted lines Z Z along the ends thereof are supposed to represent the inner edges of the chase when finished, and if the work were to be done by hand, such lines would be laid out on either side of the chase. When the work is done on my improved machine, these lines are not wanted, and are only used in the drawings for illustration. The chase is clamped upon the bed B,but by means of being arranged to clamp a chase crosswise, the bed, using of course, the finished edges of the chase in resetting the work.

The blocks K with the clamping mechanism attached, are preferably provided with dowel pins, at the bottom, that lit in holes drilled in the bed, such holes being provided to accommodate blocks K in the different positions for all standard sizes of chases; hence the resetting of theblocks is quickly done, and with accuracy, and a boy of ordinary intelligence can successfully operate this machine and can turn out better work and many times as much work as a skilled workman can turn out by hand.

The general construction of the machine to which my invention may be applied may be modified in many particulars. For instance in building my first machine, and which I have still in successful operation, I used an ordinary double-headed millingmachine, each head havinga horizontal spindle for attaching a cutter. The two spindles werein a line with each other, and the two heads bearing these spindles were adjustable in the direction from and toward each other. These spindles however, had no vertical movement, but instead, the bed was constructed to move up and down and also to feed endwlse.

This former machine I consider a perfect success, but it is more complicated and. expensive to build, than the machine illustrated in the accompanying drawings, in the manufacture of which a small sized planer 1s utilized. Hence I prefer the construction shown. Sometimes this work is partially done on an ordinary milling machine, but in such case, the cutter-spindle is in the way so that the cutter cannot be fed down through the inslde of the chase, far enough to finish the corners thereof, but, instead, leave concaved sections that have to be dressed by hand.

With my improved construction, the cutter, being located on the outer end of, and overhanging the spindles, the cutters may be fed down through the inside of a chase so as to finish the corners perfectly.

lVhat I claim is- The combination in a machine for dressing printers chases, of the movable bed which carries the chase, the mechanism for operating the same, the laterally-adj ustable hangers carrying the cutters, the mechanism for rotating said cutters, and the vertically-movable yoke carrying the adjustable hangers, and mechanism for adjusting the same above the movable bed, substantially as specified.

In testimony whereof I sign this specification, in the presence of two witnesses, this 14th day of April, 1892.
